> h3. Problem summary
> When repository encryption is enabled, replaying a DROP provenance record
> fails, with the following error appearing in the logs:
> {quote}org.apache.nifi.processor.exception.FlowFileAccessException: Failed to
> export
> StandardFlowFileRecord[uuid=df985fc5-23da-4094-8783-2e0186bcb92d,claim=StandardContentClaim

> to /opt/nifi/nifi-current/data/store/.b29633c4-324e-42fe-b3e8-1ea455fc3650
> due to java.io.EOFException: *Attempted to copy {color:#ff8b00}1048576{color}
> bytes but only {color:#ff8b00}1048197{color} bytes were available*
> {quote}
>
> I've observed that the difference between the sizes mentioned in the log is
> {+}*always 379 bytes*{+}, regardless of the length of the input file.

> With repository encryption disabled, provenance replay works as expected.
> h3. Configuration
> # NiFi v1.16.3 running as a three-node cluster in Kubernetes.
> # Each node has up to 8GB memory and 4 CPUs available to it.
> # Testing has included both NFS and ephemeral (emptyDir) storage.
> # The encryption key was generated by the following command, using the same
> JDK version:
> ## keytool -genseckey -alias key-1 -keyalg AES -keysize 256 -keystore
> repository.p12 -storetype PKCS12
> h4. nifi.properties
> {quote}nifi.repository.encryption.protocol.version=1
> nifi.repository.encryption.key.id=key-1
> nifi.repository.encryption.key.provider=KEYSTORE
> nifi.repository.encryption.key.provider.keystore.location=conf/repository.p12
> nifi.repository.encryption.key.provider.keystore.password=<password>
> {quote}
> h3. Processor group
> GenerateFlowFile processor generating 1MB random files every second to a
> PutFile processor. Have also tested with InvokeHTTP.
> h3. Other comments
> With repository encryption enabled, I am able to download files via the
> provenance UI (suggesting that encryption/decryption works). The processor
> group also performs all other actions as expected.
> Not having the ability to replay provenance records is a blocker for our
> deployment, which requires data to be encrypted at rest and in transit.
